Lists, adds, removes, locks, unlocks, or prunes git worktrees for managing multiple working trees. Returns structured data with worktree paths, branches, and HEAD commits.
AI agents call worktree to permanently remove resources in Python — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs multiple operations including 'removes' and 'prunes' git worktrees, which are irreversible destructive actions. Although it also supports read (list) and write (add, lock, unlock) operations, the most severe applicable category applies due to remove/prune capabilities. Misuse could result in loss of working tree state and uncommitted changes.

Attacks that exploit this kind of access
Lists, adds, removes, locks, unlocks, or prunes git worktrees for managing multiple working trees. Returns structured data with worktree paths, branches, and HEAD commits. It is categorised as a Destructive tool in the Python MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Python MCP server in PolicyLayer and add a rule for worktree: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Python. Nothing to install.
worktree is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the worktree rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for worktree. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
worktree is provided by the Python MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
worktree is one line of Python's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
